The annual global-construction waste is projected to exceed 2.2-billion-tonnes by 2025 (U.S.-Environmental-Protection-Agency, 2021). This waste accounts for over 30% of CO2 emissions which has severe consequences for climate-change. This waste not only has a negative impact on the environment, but it also represents a missed opportunity to recycle-or-reuse valuable materials. The construction-demolition-and-excavation industries are responsible for generating around 60% of the UK's waste, with demolition being a major contributor within the construction industry. Findings suggest construction-and-demolition(C&D) waste amount to over 100 million tonnes annually (Hughes & Salvidge, 2018), and in 2020 alone, the UK generated over 53.6 million tonnes of non-hazardous C&D waste (UK statistics on waste, 2020).Reusing materials have a significant impact on reducing embodied carbon emissions, with potential savings of up to 95% compared to purchasing new products. To address this issue, the UKGBC has implemented a Circular-Economy Guidance for Construction Clients, which includes "Maximise Reuse" as one of its guiding principles (UKGBC, 2019), alongside other policies aimed at reducing waste. The rising awareness of the built-environment sector's impact on the climate has also led to increased pressure on developers to reduce waste generation, and one of the measures implemented to achieve this is Pre-demolition audit.Pre-demolition audit is conducted to help maximise reuse & recycling of materials. While demolition is often necessary for new development and revitalization, it is important to consider the impact on the environment and take steps to minimize waste-generation. Pre-demolition audit is required to support the circular economy statement as part of the planning stage of redevelopment, to promote sustainable building practices, and identify opportunities for cost-savings. However, it is generally a time-consuming process requiring several weeks to complete, depending on the project size. Despite the benefits of pre-demolition audit, the long-time required is often seen as a burden by developers/clients who may view it as a delay in the construction process. This can lead to the temptation to skip this important stage, which can inherently have significant consequences for the environment & economy.This project (APAIR) is aimed at automating the pre-demolition audit process and improving the reusability of construction materials before demolition. APAIR aims to streamline the pre-demolition audit process, by using advanced machine-learning algorithms. it can quickly identify the reusable materials present in a building before demolition. This information is then used to determine which materials can be reused-recycled-repurposed or disposed. APAIR has the potential to revolutionize the demolition-industry.

到2025年，全球每年的建筑垃圾预计将超过22亿吨(美国环境保护局，2021年)。这些废物占二氧化碳排放量的30%以上，这会对气候变化造成严重后果。这些废物不仅对环境有负面影响，而且还错失了回收或再利用有价值的材料的机会。建筑拆迁和挖掘行业产生了英国约60%的垃圾，其中拆迁是建筑业的主要贡献者。研究结果表明，每年建筑和拆迁(C&D)废物的数量超过1亿吨(Hughes&Salvidge，2018)，仅在2020年，英国就产生了超过5360万吨非危险的C&D废物(英国废物统计，2020)。重复使用材料在减少具体化碳排放方面具有重大影响，与购买新产品相比，潜在节省高达95%。为了解决这个问题，UKGBC为建筑客户实施了循环经济指导，其中包括将“最大限度地重复利用”作为其指导原则之一(UKGBC，2019年)，以及旨在减少浪费的其他政策。建筑业对气候影响的认识不断提高，亦令发展商承受更大压力，以减少产生废物，其中一项措施是进行拆卸前审核。拆卸前审核是为了协助尽量重复使用和循环再造物料。虽然拆迁对于新的发展和振兴往往是必要的，但重要的是要考虑对环境的影响，并采取措施尽量减少废物的产生。拆卸前的审计需要支持循环经济声明，作为重建规划阶段的一部分，以促进可持续的建筑做法，并确定节省成本的机会。然而，这通常是一个耗时的过程，需要几个星期才能完成，具体取决于项目规模。尽管拆迁前审计有好处，但所需的长时间往往被开发商/客户视为一种负担，他们可能会认为这是施工过程中的延误。这可能会导致跳过这一重要阶段的诱惑，而这一阶段本身就会对环境和经济产生重大影响。该项目(APAIR)旨在实现拆迁前审计过程的自动化，并提高拆迁前建筑材料的可重用性。APAIR的目标是通过使用先进的机器学习算法来简化拆迁前审计过程。它可以在拆除前快速识别建筑物中存在的可重复使用的材料。然后，这些信息被用来确定哪些材料可以重复使用--再循环--再利用或处置。APAIR有可能给拆迁行业带来革命性的变化。
